What are the elements in beryllium chloride?
The structure of solid BeCl2 is an unusual chain polymer with two chlorine atoms bridging between the Be atoms. The ClBeCl bond angle is less than tetrahedral, at 980 . It therefore achieves an octet of electrons and has an approximate hybridisation of sp3 . The structure of liquid is dimeric with 2 chlorines bridging, Be does not achieve the octet in this. In the gas the dimer persists up to around 900 0when it is fully dissociated into the linear Cl-Be-Cl monomer. This is linear as predicted by VSEPR.
How many aluminum atoms are there in a mass of 16.2 grams?
To calculate the number of atoms in 16.2 grams of aluminum, you first need to determine the number of moles using the molar mass of aluminum (26.98 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to find the number of aluminum atoms in 16.2 grams.
How many hydrogen atoms are in 738 grams of water?
To find the number of hydrogen atoms, we need to first determine the number of water molecules in 738 grams of water. Then, using the molecular formula of water (H2O), we know that each water molecule contains 2 hydrogen atoms. Finally, we can calculate the total number of hydrogen atoms by multiplying the number of water molecules by 2.
How many atoms are in 1.7 g C?
1.7 grams * (1mole/ 12.011 grams) * (6.023x 10^23 atoms/ 1 mole) =8.525 * 10^ 22 atoms carbon round to 2 sig. figs
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
What is the formula for the ionic compound beryllium chloride?
The formula for beryllium chloride is BeCl2. It consists of one beryllium atom and two chloride atoms in a 1:2 ratio.
Does Be only have 4 electrons shared in BeCl2?
No. Beryllium has only two valence electrons and forms ionic bonds with chlorine, not covalent bonds. Beryllium atoms form 2+ ions, and chlorine atoms form 1- ions in order to form the ionic compound beryllium chloride, BeCl2.
What is the Lewis structure of BeCl2?
The Lewis structure of BeCl2 shows beryllium in the center with two chlorine atoms attached to it. Beryllium has 2 valence electrons and each chlorine has 7 valence electrons. The structure is linear with beryllium in the middle and a chlorine atom on each side.
Lewis structure of BeCl2?
The Lewis structure of BeCl2 consists of beryllium (Be) at the center with two chlorine (Cl) atoms attached to it. Beryllium has 2 valence electrons and chlorine has 7 valence electrons each. The Be atom forms two single bonds with the Cl atoms, resulting in a linear molecular geometry.
Why more stable structure for BeCl2 does not obey octet rule?
Beryllium in BeCl2 doesn't follow the octet rule because it only has 4 valence electrons and can only form 2 bonds. Thus, BeCl2 adopts a linear structure with beryllium acting as a central atom bonded to two chlorine atoms. This arrangement allows BeCl2 to achieve a stable electron configuration without needing to fill its valence shell with 8 electrons.
How many carbon atoms are in 2 grams of 1 carat diamond?
There are about 1.092 x 10^21 carbon atoms in 2 grams of 1 carat diamond. This is calculated based on the molar mass of carbon and Avogadro's number.

How many grams of hydrogen are there in 207 grams of water?
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
Why is BeCl2 soluble in water whereas group 2 elements are not?
Although the group 2 metals are not soluble in water in and of themselves, many of their compounds are. Elemental beryllium consists of neutral metal atoms while BeCl2 contains positive Be2+ ions and negative Cl- ions. The water molecule is a polar molecule, possessing a partial positive charge on the hydrogen and a partial negative charge on the oxygen. One end of the water molecule is attracted to the oppositely charge ion in BeCl2. This attraction is strong enough to pull apart the BeCl2 crystal structure.
What is the formula mass of beryllium chloride?
The formula for beryllium chloride is BeCl2. To calculate the formula mass, you need to add the atomic masses of beryllium and chlorine. The atomic mass of beryllium is about 9 and the atomic mass of chlorine is about 35.5. Therefore, the formula mass of beryllium chloride is approximately 9 + (2*35.5) = 80 grams per mole.
What is the net ionic equation of BeCl2 plus NaOH?
BeCl2(aq) + 2NaOH(aq) -> 2NaCl(aq) + Be(OH)2(s) Be(aq) + 2OH(aq) -> Be(OH)2(s) Hope this helps!
What is the ionic compound of BeCl2?
The ionic compound of BeCl2 is beryllium chloride. It is formed by the combination of beryllium (Be) and chloride (Cl) ions in a 1:2 ratio.
